  • VOA Radiogram, 17-18 December 2016: Reorganizing the organization

    Near-winter-solstice propagation has made reception of VOA Radiogram more problematic, especially in the higher frequencies (15670 and 17580), while opening up opportunities for reception south of the Equator.
    In  recent weeks, the Saturday 0930 UTC on 5865 kHz show has delivered a signal to Europe via the gray line, though usually not good enough for successful decoding. If you are in Europe, keep trying this transmission, at least into February.  
    For European listeners, this time of year the best opportunity for reception might, ironically, be the Sunday 0230 UTC broadcast on 5745 kHz. It’s nominally beamed to the Caribbean, and in the middle of the night in Europe. Audacity’s timer record feature can be helpful here. Just leave your radio on all night – and sleep well!
    This weekend’s VOA Radiogram has some interesting items, including a story about the future of US international broadcasting, including VOA. If reception is difficult – a likely scenario – one item is in Olivia 64-2000. It might decode successfully even if you can barely hear the signal through your speaker or see it on the waterfall.
    For best Olivia 64-2000 performance, turn Fldigi’s squelch (SQL) off. And to keep the center audio frequency from wandering, Configure > IDs > RsID > turn off Searches passband. Set your audio frequency to 1500 Hz, and it will wander no more than +/- 200 Hz.
    Here is the lineup for VOA Radiogram, program 194, 17-18 December 2016, all in MFSK32 except where noted:
